Retrieve a obs_source_info from a obs_source_t?

[ggregoire]

Hi!

I was wondering if you could maybe help me with this.

I'm trying to retrieve a obs_source_info from a obs_source_t but can't figure how to. Both types are documented on the same page so I guess they are related. I can't access the obs_source_info's attributes directly on obs_source_t (i.e. AttributeError: 'SwigPyObject' object has no attribute '…') but I can't find any method like get_source_info either.

I am especially interested in the media_get_time attribute from obs_source_info.

Here is the code I have so far.

I retrieve the source of a scene item (i.e. obs_source_t) and I'd would like to get its obs_source_info:

import obspython as obs

current_scene = obs.obs_frontend_get_current_scene() 

print("current_scene", current_scene) # <Swig Object of type 'obs_source_t *' at 0x12...>

if current_scene:
    scene = obs.obs_scene_from_source(current_scene)
    scene_item = obs.obs_scene_find_source(scene, "stream_source")

    print("scene_item", scene_item) # <Swig Object of type 'obs_sceneitem_t *' at 0x12...>

    if scene_item:
        source = obs.obs_sceneitem_get_source(scene_item)

        print("source", source) # <Swig Object of type 'obs_source_t *' at 0x12...>
        print("source media_get_time", source.media_get_time)  # AttributeError: 'SwigPyObject' object has no attribute 'media_get_time'

		# How to get a obs_source_info then?

		# …

Thanks!

Try sourceSettings = obs.obs_source_get_settings(source). Maybe, you have to do something like this (code is only to guide you):

source_name = 'something.mp4'
source = obs.obs_get_source_by_name(source_name)
sourceSettings = obs.obs_source_get_settings(source)
newSettings = obs.obs_data_create()

# These can or not be
# obs.obs_data_set_string(newSettings, "sourceName", obs.obs_source_get_name(source))
# obs.obs_data_set_string(newSettings, "sourceId", obs.obs_source_get_id(source))
# obs.obs_data_set_double(newSettings, "sourceType", obs.obs_source_get_type(source))
obs.obs_data_set_obj(newSettings, "sourceSettings", sourceSettings)
retorno = obs.obs_data_get_json(newSettings)
print(retorno)

obs.obs_source_release(source)
obs.obs_data_release(newSettings)

There are rough edges regarding SWIG usage, see this and this. One workaround is to use FFI.
Alternative solution to your code, would be using obs_source_media_get_time . Note, some functions are not documented in the sphinx docs, for that use auto generated from obspython export.md document and Ctrl + f

@upgradeQ Thank you! I just tested obs_source_media_get_time(source) and it works as expected!
